Abstract
【解決手段】本発明における摩耗性被覆に使用されるセラミックシール材料は、ジスプロシア(Dy2O3)とジルコニア(ZrO2)とを含む。被覆は多孔性であり、その多孔部は、プラスチック層または一過性の相によってある程度導入される。ジスプロシアとジルコニアとを含む摩耗性シール被覆は、改善された耐熱衝撃性及び難焼結性を示し、少なくとも相対ブレード速度と被覆多孔度のある状況で処理されていない剥き出しのタービンブレードによって許容範囲まで磨耗されることができる。ジスプロシアとジルコニアとを含むセラミック摩耗性シール被覆は、1200℃まで使用されることができる。

Description
(1)摩耗性グリット:50μmの粒径のアルミニウム酸化物を600g、
(2)衝突角430:20°、
(3)スタンドオフ距離450:100mm。
トップコート浸食の最も深い点460は、ボールマイクロメーターで測定され、以下の式1から浸食度数E(erosion number)が計算された。
E=試験時間(s)/(浸食深さ(インチ)×1000)・・・(式1)
浸食度数Eは、s/milで表され、トップコート厚さの1/1000インチ(25.4μm)を浸食するまでの時間(秒)を表す。これによれば、より高い浸食度数Eは、より良い耐浸食性を意味する。
